COLLAIE'SIBLE CRATE.

Application filed October 8, 1920. Serial No. 415,520.

To @ZZ whom t may concern:

Be it known that I, EDWARD Ii. RUPRACHT, of West Monroe, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Collapsible Crates, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in collapsible crates.

The primary object of the invention is the production of a collapsible crate of simple construction and that can be assembled without the use of nails, screws or fastening means other than the devices attached to the sides of the crate and which can be readily and easily assembled and disassembled and be comparatively rigid in its assembled condition.

Other objects and advantages relate to the details of construction as will more fully appear from the following description taken in connection with the accompanying drawings, in which Figure 1 is a perspective view of the crate.

Fig. 2 is a view of a portion of one of the end walls of the same.

TFig. 3 is a section taken on line 3 3,

lig. 1.

Fig. 4 is a view of a portion of either the top or bottom wall of the crate.

Fig. 5 is a view partially in section of a portion of the interlocking devices for securing the parts together.

Fig. 6 is a view of a portion of one of the side parts of the box.

As shown, the crate consists of a similarly constructed top and bottom wall 1 a pair of similarly constructed end walls 2 and a pair of similarly constructed side walls 3, all secured together in the manner hereinafter described. 'Ihe top and bottom walls 1 may, as shown, be formed of a series of cross boards 4 having their opposite ends respectively connected by metallic strips 5, which strips extend a short distance beyond the ends of the cross boards 4 and are each formed with a roll or bead 6 which may preferably inclose a reinforcing wire 7. 'Ihese strips are each provided with a series of openings or perforations at the base of the bead 6 to receive the attaching members carried by the end walls 2.

These end walls 2 may each consist of a ,Suitable board B reinforced at its edges longitudinally extending metallic strips 9 which strips preferably project a short distance beyond'the adjacent edges of the board and are formed with a roll or bead 10 having at spaced intervals slots or open ings 11 formed therein for the passage of U-shaped clamping devices 12 formed integrally from a wire 13 extending through and reinforcing the bead 9. These clamping devices 12 may be of any suitable number and may be spaced the required distance to conform with and be extended through the openings 14 formed at the base of the bead 6, and when so passed through said open ings, they are returned bent around the bead 6 in the manner shown in Fig. 3 to rigidly secure the parts together.

The other edges of the board 8 are provided with laterally extending metallic strips 15 extending beyond their adjacent edges and terminating in a bead 16, at the base of which are formed a series of slots or openings 17 for the reception of the U-shaped lugs or clamping devices 18 constructed similarly in all respects to the devices 12 and formed of a portion of an integral wire extending through a bead 19 formed in connection with themetallic strips 2O which metallic strips constitute connecting means for the ends of the strips 21 forming the side pieces 3. The top and bottom parts 1 are not directly connected to the side pieces 3 so that by loosening one end of either the top or bottom section it may be hingedly moved about the other end to permit the insertion or removal of articles to and from the box.

The clamping devices 12 and 18 are as best shown in Fig. 3, extended through the respective openings in the adjacent parts and returned bent about the particular wire carrying bead.

From the above drawings and description, the construction of the box and its parts will be readily understood, and although I have described a specific construction, form and relation of the parts, I do not desire to limit myself to the same except as specifically set forth in the appended claims.

What I claim is:

1. A collapsible crate including two sections, each having metallic reinforcing members at their edges, one of said metallic reinforcing members formed with a bead having a series of perforations, a wire ex'f tended through said bead, and having U- shaped clamping parts projecting through said perforations, the other of said metallic reinforcing members formed with a series of perforations through which clamping parts are extended and return bent to secure the parts together. Y

2. A collapsible crate comprising two separable sections, each section having a metallic edged portion, one of said metallic edged portions formed with a series of openings and the other metallic edged portion carrying an integral Wire bent to form a series of projecting loops conforming in number to the openings through the other metallic edged portion and extended through tsaid openings to secure the parts together.

In Witness whereof I have hereunto Set my hand this 26th day of September 1920. 20
